OVERVIEW

Group total recordable injury frequency rate (TRIF) at the quarter end was 5.9 (30 June 2018: 5.5). The focus continues to be on improving the safety culture and embedding critical controls at operational sites.

Group gold production for the September 2018 quarter was 200,218 ounces (Jun qtr: 202,254oz) at an AISC of A$885/oz (Jun qtr: A$846/oz). Using the average AUD:USD exchange rate for the quarter of 0.7315, Group AISC equated to US$647/oz – ranking Evolution as one of the lowest cost gold producers in the world.

Evolution delivered operating mine cash flow of A$196.9 million (Jun qtr: A$221.9M) and net mine cash flow of A$129.3 million (Jun qtr: A$136.0M). Group capital expenditure was A$67.7 million (Jun qtr: A$85.9M).

As at 30 September 2018, gross debt outstanding under the Senior Secured Syndicated Term Facility D was A$375.0 million. Net bank debt stood at A$78.2 million (Jun qtr: A$71.8M). A fully franked dividend of 4 cents per share equating to A$67.7 million was declared and paid during the quarter. The Group cash balance decreased to A$296.8 million (Jun qtr: A$323.2M).

Ernest Henry delivered a standout operating performance producing 25,638oz at an AISC of A$(617)/oz generating net mine cash flow of A$53.8 million.

The capital projects at Cowal, which are a key driver of Evolution’s organic growth, progressed well during the quarter. Material movement in the Stage H cutback was slightly ahead of plan. The Float Tails Leach project, which is expected to increase recoveries by 4 – 6%, is on schedule for commissioning in the December 2018 quarter. Subsequent to the end of the September quarter Cowal also received regulatory approval to expand the plant’s processing rate by 31% from 7.5Mtpa to 9.8Mtpa.

Successful drilling at Cowal’s GRE46, GRE46 South and E41W continues to highlight the high grade nature of this mineralised system. Strong results were also returned from Mungari drill programs including high grade intersections at Scottish Archer and Castle Hill.

In July 2018 Evolution signed an agreement with Norton Gold Fields to restructure ownership of the Castle Hill gold deposit. Evolution’s now owns 100% of this project with Ore Reserves of 236,000 ounces which will provide a material extension to the operating life at Mungari.

In September 2018 Evolution entered into an earnin joint venture agreement with Andromeda Metals over the ~520km[2 ] Drummond exploration project. The project is situated close to Evolution’s Mt

Carlton gold mine and leverages the Company’s expertise in epithermal gold deposits.

Evolution’s Investor Day held in Sydney on 4 September provided a comprehensive Company update including a three-year production and cost outlook. An ‘on demand’ webcast can be viewed at: evolutionmining.com.au/webcasts-media/

December 2018 quarter gold production is expected to be between 185,000 – 195,000 ounces.

OPERATIONS

Cowal, New South Wales (100%)

Cowal delivered another strong quarter producing 61,260oz of gold at an AISC of A$958/oz (Jun qtr: 63,777oz, AISC A$976/oz). Plant throughput of 1,921kt was achieved. TRIF increased from 3.3 to 4.0 and was down 27% year-on-year from 5.5.

Mine operating cash flow for the quarter was A$52.8 million. Net mine cash flow was A$24.0 million (Jun qtr: A$5.8M) post sustaining capital of A$9.3 million and major capital of A$19.5 million. Major capital was associated with growth projects including the Stage H, Float Tails Leach (FTL) project and early works on the new Integrated Waste Landform tailings facility.

Stage H material movement is slightly ahead of plan. Mining activities have moved from free digging of the oxides into fresh rock that now requires drill and blast.

The FTL project is on track to be fully commissioned during the December 2018 quarter.

Subsequent to the end of the quarter, regulatory approval was granted for the Modification 14 development application. Key aspects of this modification include increasing plant processing rate from 7.5Mtpa to 9.8Mtpa and the use of an Integrated Waste Landform as a tailings solution for the life of mine. This approval is an important milestone toward achieving a sustainable 300,000oz per annum production profile.

Mungari, Western Australia (100%)

Mungari produced 35,120oz of gold at an AISC of A$1,120/oz (Jun 2018 qtr: 30,169oz, AISC A$1,235/oz). TRIF decreased from 8.5 to 7.5 with one Medical Treatment Injury (MTI) occurring during the quarter.

Mine operating cash flow for the quarter was A$22.8 million (Jun qtr: A$11.8M). Net mine cash flow was A$17.4 million (Jun qtr: A$3.3M) post sustaining capital of A$2.5 million and major capital of A$2.9 million. The major capital was significantly lower than the prior quarter (Jun qtr: A$6.2M) due to lower capital waste movement in the White Foil open pit.

The Frog’s Leg Underground mine produced 138kt of ore at a grade of 5.41g/t gold. Total development was 310m with a focus on progressing a drill drive into the hanging wall.

The White Foil open pit Stage 3 cutback progressed on plan and continued into an operating phase with volumes of capital waste declining as the strip ratio falls. Total material movement was 2.1Mt including 373kt of ore at a grade of 1.47g/t gold.

The process plant continued to perform well with 402kt of ore processed at an average grade of 2.89g/t gold. Plant utilisation was 94.6%.

A separate regulatory approval to commence development of the GRE46 exploration decline is expected to be received in the December 2018 quarter.

OPERATIONS

Mt Carlton, Queensland (100%)

Mt Carlton produced 26,197oz of payable gold comprised of 19,378oz contained in 14,223 dry metric tonnes (dmt) of gold concentrate and 6,819oz in gold doré (Jun qtr: 26,708oz, 20,908oz in concentrate and 5,800oz gold doré). AISC of A$831/oz (Jun qtr: A$712/oz) increased due to lower copper and silver by-product credits and higher sustaining capital with the construction of the Stage 5 Tailings Storage Facility wall raise. TRIF continued to improve, reducing from 3.9 to 3.8.

Operating mine cash flow of A$25.1 million and net mine cash flow of A$16.6 million (Jun qtr: A$35.2M) was generated post sustaining and major capital of A$8.5 million.

A total of 196kt of V2 ore grading 5.47g/t gold was treated. Processing plant recoveries were 87.7%. An upgrade to the concentrate thickener which was completed in July will improve plant performance going forward.

Mining continued to focus on Stage 3 ore ahead of the wet season. Permitting approval for the Stage 4 cut back is anticipated in the December 2018 quarter with pre-stripping activities planned to commence shortly thereafter.

Mt Rawdon, Queensland (100%)

Mt Rawdon produced 29,712oz of gold at an AISC of A$1,168/oz (Jun qtr: 31,244 oz, AISC A$934/oz). TRIF increased from 5.1 to 6.7 with one MTI occurring during the quarter.

Mine operating cash flow for the quarter was A$25.3 million (Jun qtr: A$27.1M). Net mine cash flow was A$11.8 million (Jun qtr: A$22.5M) post sustaining and major capital of A$13.6 million. The majority of the capital spend was on the Stage 4 cutback (A$11.0M).

Mining activities were focussed on waste material in Stage 4 and installing additional ground support in the western area of the pit.

Ore mined of 236kt at an average grade of 1.70g/t was higher than planned due to better than expected availability of ore from the bottom of the pit. The plant processed 845kt at an average head grade of 1.20g/t Au. Plant utilisation was 96%.

Over the coming two quarters the focus will continue to be on the Stage 4 cutback. Ore processed during this time will come predominately from stockpiles.

In early October 2018 the Board approved development of the Mt Carlton underground mine which will allow production from the high grade Link zone to be brought forward. Commencement of the development remains subject to regulatory approval. First ore from the underground is planned to be delivered in FY21. Capital expenditure is estimated to be approximately A$60 million of which ~A$10 million will be spent in FY19 and the remaining ~A$50 million over FY20-FY22. The FY19 component was included in prior FY19 major capital guidance of A$25 – A$30 million.

FINANCIALS

The September 2018 quarter saw all operations continuing to be cash flow positive after meeting their operating and capital needs.

A total of A$67.7 million for the FY18 final full franked dividend of 4 cents per share was paid to shareholders during the quarter.

Evolution sold 196,021oz of gold at an average gold price of A$1,662/oz (Jun 2018 qtr: 208,239 oz at A$1,675/oz). Deliveries into the hedge book totalled 37,500 oz at an average price of A$1,681/oz with the remaining 158,521oz of gold delivered on spot markets at an average price of A$1,657/oz.

Evolution generated operating mine cash flow of A$196.9 million (Jun 2018 qtr: A$221.9M). The lower cash flow was due to timing of gold sales in the September quarter and a lower realised copper price.

Net mine cash flow was strong at A$129.3 million (Jun 2018 qtr: A$136.0M). This was after investing a total of A$67.6 million in capital, split between A$27.3 million in sustaining capital and A$40.3 million in major project capital.

Cowal continued to deliver an exceptional financial performance with A$24.0 million in net mine cash flow (Jun 2018 qtr: A$5.8M) despite the heavy investment in future production via the Stage H development.

Ernest Henry net mine cash flow of A$53.8 million was lower than the June 2018 quarter, due mainly to a lower achieved copper price.

Mungari net mine cash flow of A$17.4 million was a significant improvement on the June quarter (A$3.3M) due to higher production and a lower capital spend.

EXPLORATION

Exploration highlights

  • Cowal

  • Excellent drilling results continue at GRE46 where new assays and interpretations have defined the high-grade Dalwhinnie Lode including an intersection of 3.0m at 69.9g/t Au

  • At GRE46 South a high-grade intersection of 10.5m (6.8m etw) grading 11.71g/t Au was returned from a new area south of the pit

  • Further drilling at E41W is confirming the potential to expand the resource – deep high-grade intersections below the E41W resource pit shell including 7.7m (4.4m etw) grading 11.71g/t Au suggests the potential for underground resources

  • Mungari

  • Further exploration drilling at Scottish Archer has intersected high-grades including 4.0m (3.9m etw) grading 13.24g/t Au

  • Resource extension drilling at Castle Hill intersected high grades including 7.2m (5.7m etw) grading 22.51g/t Au at the base of the A$1,800/oz resource shell which indicates potential upside

  • Drummond Project – Evolution entered into an earn-in joint venture agreement with Andromeda Metals Limited (ASX:AND) for 80% of the highly prospective Drummond exploration project

  • Total drilling of 32,435m (resource definition) and 47,616m (discovery) was completed during the quarter. Evolution’s exploration tenement holdings in Australia stand at 7,796 km[2]

Cowal, New South Wales (100%)

During the September quarter drill testing was completed at the GRE46 and E41 West targets. A total of 42 holes for 14,910m were completed with 23 holes at GRE46 and 21 holes at E41 West (Figure 1).

EXPLORATION

Galway Regal E46 (GRE46)

During the quarter, a program of infill drilling was completed targeting the deeps area of the GRE46 underground resource to confirm geological and grade continuity. In addition, exploration drilling targeting extensions to the system intersected high grade mineralisation 750m to the south of previous drilling on the GRE46 trend.

Infill drilling of the GRE46 underground resource identified a new zone of high-grade mineralisation associated with the Dalwhinnie Sill. The Dalwhinnie Sill is located in the footwall to the main GRE46 resource, with most historic drilling pulling up short of this position. Significant results from Dalwhinnie during the quarter include 3.0m (2.3m etw) grading 69.9g/t Au from 883m (hole 1535DD331H)[1] .

Drilling of the main GRE46 resource also returned strong results previously reported including[1] :

  • 29.0m (20.1m etw) grading 5.35g/t Au from 754m and 12.0m (8.3m etw) grading 14.14g/t from 792m (hole 1535DD331G)

  • 33.0m (20.8m etw) grading 3.43g/t Au from 751m and 23.0m (14.8m etw) grading 6.82 g/t Au from 806m (hole 1535DD331E)

  • 24.0m (17.8m etw) grading 1.71g/t Au from 712m, 28.0m (22.9m etw) grading 3.82g/t Au from 766m and 5.0m (4.2m etw) grading 16.44g/t Au from 806m (hole 1535DD331D)

  • 32.0m (20.1m etw) grading 2.63g/t Au from 753m (hole 1535DD331B)

  • 10.0m (6.8m etw) grading 1.66g/t Au from 747m (hole 1535DD331C)

In addition, recent exploration drilling has intersected high grade mineralisation 750m to the south along the GRE46 trend. As of the end of the quarter, five drill holes were completed, with partial results received for one hole.

Drill hole 1535DD346 intersected a zone of quartz-carbonate-pyrite-chalcopyrite veining. Significant intersections for this interval were:

  • 10.5m (6.8m etw) grading 11.71g/t from 362m including 2.6m (1.7m etw) grading 33.40g/t from 365 (hole 1535DD346)

E41 West

Drilling at E41 West included resource definition and resource extension drilling. Resource definition drilling focussed on infilling gaps within the current A$1,800/oz resource shell, and around the limits of the A$1,800/oz resource shell where drilling might limit the resource optimisation. A total of 16 drill holes were completed including holes for geotechnical and metallurgical test work. Significant results include:

  • 8.0m (4.6m etw) grading 5.32g/t from 361m and 40.0m (22.9m etw) grading 1.03g/t from 387m (hole E41D2817)

  • 41.4m (16.2m etw) grading 1.15g/t from 352m (hole E41D2625A)

  • 43.0m (27.1m etw) grading 1.39g/t from 380m and 7.7m (4.9m etw) grading 11.71g/t from 455.28m (hole E41D2826)

==> picture [334 x 179] intentionally omitted <==

Figure 5: Cross section of E41D2826 showing mineralised intervals in extensional drilling below current A$1,800/oz resource shell

From resource extension drilling, high grade mineralisation in hole E41D2826 (7.7m (4.4m etw) grading 11.71g/t Au from 455m) is associated with the Killara structure, for which high grade intervals were reported in the previous quarter (19.0m (8.0m etw) grading 4.4g/t Au in E41D2811 and 4.0m grading 5.1g/t in E41D2812)[2] . The results suggest underground potential exists below the current pit resource.

Ora Banda (Perimeter and Frontier)

In the Ora Banda area significant intercepts continue to be received at Perimeter. Drilling has now intersected mineralisation along a 1,600m-long corridor. Sixteen holes were completed testing both strike and down dip extensions. In addition, a new parallel strongly mineralised structure called Frontier has been intersected in drilling 400m west of Perimeter. The area is being re-evaluated in the context of a larger scale mineral system.

Scottish Archer

Nine holes were drilled at Scottish Archer to test the extents of a high-grade zone identified in previous drilling (Figure 7 – Long Section). Best intercepts include:

  • 4.0m (3.9m etw) grading 13.24g/t Au from 335m (EVRC0476)

  • 1.0m (1.0m etw) grading 30.00g/t Au from 89m (EVRC0477)

  • 2.0m (1.7m etw) grading 5.86g/t Au from 334m (EVRC0472)

Resource Definition

During the quarter 9,775m of resource definition drilling was completed across four projects. Most of the drilling occurred at Castle Hill following the restructure of ownership in July 2018. The Castle Hill project is made up of several prospects that optimise within one pit shell and a number of other satellite pits.

Castle Hill

Twenty holes were completed at the Castle Hill project. The purpose was to improve the geological interpretation and resource estimation by infilling areas not covered by historical drilling and de-risking high-grade zones near the base of the A$1,350/oz reserve pit shell. Diamond drilling also targeted resource conversion at Outridge which sits on the eastern side of the A$1,350/oz pit shell and was informed by mostly historic RC data. Best intercepts include:

Castle Hill:

  • 7.2m (5.8m etw) grading 22.51g/t Au from 287m (CAHD017)

  • 16.0m (14.4m etw) grading 3.87g/t Au from 80m (CAHD014)

  • 1.4m (1.2m etw) grading 18.53g/t Au from 290m (CAHD011)

Outridge:

  • 9.4m (7.5m etw) grading 8.55g/t Au from 67m (OUTD024)

Assay results from CAHD017 and CAHD011 returned high grades at the base of the A$1,800/oz resource shell and indicate potential upside.

EXPLORATION

Frog’s Leg

Development of the drill platform which will be utilised for drilling below the current workings has progressed well and is scheduled for completion during November 2018. Underground drilling will then commence and is expected to take approximately six weeks to complete.

Cracow, Queensland (100%)

Resource Definition

More than 13,727m of resource definition drilling was completed with three underground diamond drills focusing on resource conversion and high priority extensional underground targets. The best results were returned from the Killarney structure where mineralisation is continuing to be defined both down dip and along strike to the south of the currently defined resource.

Drummond Project, Queensland (earning 80%)

Evolution entered into an earn-in joint venture agreement with Andromeda Metals Limited (ASX:AND) over the Drummond exploration project.

Drummond is an early-stage gold exploration project located in northern Queensland covering ~520km[2] . The project is approximately 140km south of Townsville and 50km southwest of Evolution’s Mount Carlton operation (see Figure 8). Outcropping gold-bearing veins of the same style and scale to the nearby Pajingo gold-silver deposit occur within the project. Vein textures at several prospects in the project suggest the system is largely preserved, and that the most prospective level for gold mineralisation remains untested by drilling.

Key terms of the agreement:

  • Stage 1: Evolution can earn a 51% interest in the Drummond project by making a cash payment of A$300,000 to Andromeda and spending A$2 million on exploration over a two-year period

  • Stage 2: Evolution can earn a further 29% (for a total of 80%) by making an additional cash payment of A$200,000 and spending A$4 million on exploration over two years

Cowal Section 1 Sampling Techniques and Data

Cowal Section 1 Sampling Techniques and Data Cowal Section 1 Sampling Techniques and Data
Criteria Explanation Commentary
Sampling techniques Nature and quality of sampling (e.g. cut
channels, random chips, or specific
specialised
industry
standard
measurement tools appropriate to the
minerals under investigation, such as
downhole gamma sondes, handheld
XRF instruments, etc.). These examples
should not be taken as limiting the broad
meaning of sampling.
Include reference to measures taken to
ensure sample representation and the
appropriate
calibration
of
any
measurement tools or systems used.
Aspects of the determination of
mineralisation that are material to the
Public Report.
In cases where ‘industry standard’
work has been completed this would be
relatively
simple
(e.g.
‘reverse
circulation drilling was used to obtain 1
m samples from which 3 kg was
pulverised to produce a 30 g charge for
fire assay’). In other cases, more
explanation may be required, such as
where there is coarse gold that has
inherent sampling problems, or unusual
commodities/mineralisation types (e.g.
submarine nodules).

Holes in this report consist of conventional diamond core
drilling.

Drill holes were positioned strategically to infill gaps in the
existing drill data set and test continuity of known
lodes/mineralised structures. Collar and down hole surveys
were utilised to accurately record final locations. Industry
standard sampling, assaying and QA/QC practices were
applied to all holes.

Prior to 2018 drill core was halved with a diamond saw in 1 m
intervals, irrespective of geological contacts. Since 2018
Sampling to lithological contacts has been implemented.
Oxide material that was too soft and friable to be cut with a
diamond saw was split with a chisel. Core was cut to preserve
the bottom of hole orientation mark and the top half of core
sent for analysis to ensure no bias is introduced. RC samples
were collected directly from a splitter at the drill rig.

Sample preparation was conducted by SGS West Wyalong
and ALS Orange. Sample preparation consisted of:

Drying in the oven at 105ºC; crushing in a jaw crusher; fine
crushing in a Boyd crusher to 2-3mm; rotary splitting a 3kg
assay sub-sample if the sample is too large for the LM5 mill;
pulverising in the LM5 mill to nominal; 90% passing 75 µm;
and a 50g fire assay charge was taken with an atomic
absorption (AA) finish. The detection limit was 0.01 g/t Au.
Drilling techniques Drill type (e.g. core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details
(e.g. core diameter, triple or standard
tube, depth of diamond tails, face-
sampling bit or other type, whether core
is oriented and if so, by what method,
etc.).

Diamond drill holes were drilled HQ diameter through the
clay/oxide and NQ diameter through the primary rock to end
of hole.

All core in this report has been drilled since 2009 and has
been oriented using accepted industry techniques at the time.
Drill sample recovery Method of recording and assessing core
and chip sample recoveries and results
assessed.
Measures taken to maximise sample
recovery
and
ensure
representative
nature of the samples.
Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
preferential
loss/gain
of
fine/coarse
material.

Provisions are made in the drilling contract to ensure that hole
deviation is minimised, and core sample recovery is
maximised. Core recovery is recorded in the database. There
are no significant core loss or sample recovery issues. Core
is reoriented and marked up at 1m intervals. Measurements
of recovered core are made and reconciled to the driller’s
depth blocks, and if necessary, to the driller’s rod counts.

There is very no apparent relationship between core-loss and
grade.

Logging Whether core and chip samples have
been geologically and geotechnically
logged to a level of detail to support
appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel etc.) photography.
The total length and percentage of the
relevant intersections logged.

Geologists log core for lithology, alteration, structure, and
veining. Logging was done directly onto laptop computers via
LogChief software which is validated and uploaded directly
into the Datashed database.

The Cowal logging system allows recording of both a primary
and a secondary lithology and alteration. Geologists also
record the colour, texture, grain size, sorting, rounding, fabric,
and fabric intensity characterising each lithological interval.

The logged structures include faults, shears, breccias, major
veins, lithological contacts, and intrusive contacts. Structures
are also recorded as point data to accommodate orientation
measurements.

Structural measurements are obtained using a core
orientation device. Core is rotated into its original orientation,
using the Gyro survey data as a guide. Freiberg compasses
and Kenometer Core Orientation tools are used for structural
measurements.

Geologists log vein data including vein frequency, vein
percentage of interval, vein type, composition, sulphide
percentage per metre, visible gold, sulphide type, and
comments relative to each metre logged.

Geotechnical logging is done by field technicians and
geologists. Logging is on a per metre basis and includes
percentage core recovery, percentage RQD, fracture count,
and an estimate of hardness. The geotechnical data is
entered into the database.

All drill core, once logged, is digitally photographed on a core
tray-by-tray basis. The digital image captures all metre marks,
the orientation line (BOH) and geologist’s lithology, alteration,
mineralogy, and other pertinent demarcations. The geologists
highlight geologically significant features such that they can
be clearly referenced in the digital images.

sampled.

Diamond Core is cut with a diamond saw or chisel. Core is cut
to preserve the bottom of hole orientation mark and the top
half of core is always sent for analysis to ensure no bias is
introduced.

In 2003 Analytical Solutions Ltd conducted a Review of
Sample Preparation, Assay and Quality Control Procedures
for Cowal Gold Project. This study, combined with respective
operating company policy and standards (North Ltd,
Homestake, Barrick and Evolution) formed the framework for
the sampling, assaying and QAQC protocols used at Cowal
to ensure appropriate and representative sampling.

Results per interval are reviewed for half core samples and if
unexpected or anomalous assays are returned an additional
quarter core may be submitted for assay.

residue samples. A blank is submitted 1 in every 38 samples,
CRM’s are submitted 1 in every 20 samples. The frequency
of repeat assays is set at 1 in 30 samples.

All sample numbers, including standards and duplicates, are
pre-assigned by a QA/QC Administrator and given to the
sampler on a sample sheet. The QA/QC Administrator
monitors the assay results for non-compliance and requests
action when necessary. Batches with CRM’s that are outside
the ±2SD acceptance criteria are reviewed and re-assayed if
definitive bias is determined or if re-assay will make a material
difference.

Material used for blanks is uncertified, sourced locally,
comprising fine river gravel which has been determined to be
below detection limit. A single blank is submitted every 38
samples. Results are reviewed by the QA/QC Administrator
upon receipt for non-compliances. Any assay value greater
than 0.1 g/t Au will result in a notice to the laboratory. Blank
assays above 0.20 g/t Au result in re-assay of the entire batch.
The duplicate assays (Au2) are taken by the laboratory during
the subsampling at the crushing and pulverisation stages. The
results were analysed using scatter plots and relative
percentage difference (RPD) plots. Repeat assays represent
approx. 10% of total samples assayed. Typically, there is a
large variance at the lower grades which is common for low
grade gold deposits, however, the variance decreases to less
than 10% for grades above 0.40 g/t Au, which is the cut-off
grade used at Cowal.

Approximately 5% of the pulps, representing a range of
expected grades, are submitted to an umpire assay laboratory
(ALS Orange) to check for repeatability and precision.
Analysis of the data shows that the Principal Laboratory is
performing to an acceptable level.

Discuss any adjustment to assay data

No dedicated twinning drilling has been conducted for this drill
program.

Cowal uses DataShed software system to maintain the
database. Digital assay results are loaded directly into the
database. The software performs verification checks including
checking for missing sample numbers, matching sample
numbers, changes in sampling codes, inconsistent “from-to”
entries, and missing fields. Results are not entered into the
database until the QA/QC Administrator approves of the
results. A QA/QC report is completed for each drill hole and
filed with the log, assay sheet, and other appropriate data.
Only the Senior Project Geologist and Database Manager
have administrator rights to the database. Others can use and
sort the database but not save or delete data.
Location of data
points
Accuracy and quality of surveys used to
locate drillholes (collar and downhole
surveys), trenches, mine workings and
other locations used in Mineral Resource
estimation.
Specification of the grid system used.
Quality and adequacy of topographic
control.

All drill hole collars were surveyed using high definition DGPS.
All drill holes were surveyed using a downhole survey camera.
The first survey reading was taken near the collar to
determine accurate set up and then at regular intervals
downhole.

On completion of each angled drill hole, a down hole
gyroscopic (Gyro) survey was conducted. The Gyro tool was
referenced to the accurate surface surveyed position of each
hole collar.

The Gyro results were entered into the drill hole database
without conversion or smoothing.

An aerial survey was flown during 2003 by AAM Hatch. This
digital data has been combined with surveyed drill hole collar
positions and other features (tracks, lake shoreline) to create
a digital terrain model (DTM). The survey was last updated in
late 2014.

In 2004, Cowal implemented a new mine grid system with the
assistance of AAM Hatch. The current mine grid system
covers all areas within the ML and ELs at Cowal with six digits.

Whether
the
data spacing
and
distribution is sufficient to establish the
degree of geological and grade continuity
appropriate for the Mineral Resource and
Ore Reserve estimation procedure(s) and
classifications applied.
Whether sample compositing has been
applied.

The exploration drillholes reported in this report are targeted
to test for continuity of mineralisation as interpreted from
previous drilling. It is not yet known whether this drilling is
testing the full extent of the mineralised geological zones. All
drilling prior to 2018 is sampled at 1 m intervals down hole.
Lithological based sampling was implemented in 2018 with a
maximum sample length of 1m and a minimum sample length
of 0.3m to avoid sampling across geological boundaries.
Orientation of data in
relation to geological
structure
Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the extent to which this is
known, considering the deposit type.
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.

Diamond holes were positioned to optimise intersection
angles of the target area. In respect of the drilling at E41W
drilling is targeted to drill at right angles to the dominant vein
direction however the extent of the vein package is currently
unknown.

The Drilling at Galway Regal is oriented perpendicular to the
known mineralised package.
Sample security The measures taken to ensure sample
security.

Drill contractors are issued with drill instructions by an
Evolution geologist. The sheet provides drill hole names,
details, sample requirements, and depths for each drill hole.
Drill hole sample bags are pre-numbered. The drill holes are
sampled by Evolution personnel who prepare sample
submission sheets. The submission sheet is then emailed to
the laboratory with a unique submission number assigned.
This then allows individual drill holes to be tracked.

An SGS West Wyalong (SGS) representative collects the
samples from site twice daily, however, if samples are being
sent to another laboratory a local freight company is used to
collect the samples from site and deliver them to the
laboratory. Upon arrival, the laboratory sorts each crate and
compares the received samples with the supplied submission
sheet. The laboratory assigns a unique batch number and
dispatches a reconciliation sheet for each submission via
email. The reconciliation sheet is checked, and any issues
addressed. The new batch name and dispatch information is
entered into the tracking sheet. The laboratory processes
each batch separately and tracks all samples through the
laboratory utilising the LIMS system. Upon completion, the
laboratory emails Standard Industry Format (SIF) files with the
results for each batch to Evolution personnel.

The assay batch files are checked against the tracking
spreadsheet and processed. The drill plan is marked off
showing completed drill holes. Any sample or QA/QC issues
with the results are tracked and resolved with the laboratory.
Audits or reviews The results of any audits or reviews of
sampling techniques and data.

QA/QC Audits of the Primary SGS West Wyalong Laboratory
are carried out on an approximately quarterly basis and for
the Umpire ASL Orange Laboratory approximately on a six-
monthly basis. Any issues are noted and agreed remedial
actions assigned and dated for completion.

Numerous internal audits of the database and systems have
been undertaken by site geologists and company technical
groups from North Ltd, Homestake, Barrick and Evolution.
External audits were conducted in 2003 by RMI and QCS Ltd.
and in 2011 and 2014 review and validation was conducted
by RPA. MiningOne conducted a review of the Cowal
Database in 2016 as part of the peer review process for the
Stage H Feasibility Study. Recent audits have found no
significant issues with data management systems or data
quality.

The Cowal Mine is located on the western side of Lake
Cowal in central New South Wales, approximately 38 km
north of West Wyalong and 350 km west of Sydney. Drilling
documented in this report was undertaken on ML1535. This
Lease is wholly owned by Evolution Mining Ltd. and CGO
has all required operational, environmental and heritage
permits and approvals for the work conducted on the Lease.
There are not any other known significant factors or risks
that may affect access, title, or the right or ability to perform
further work programs on the Lease.

The Cowal region has been subject to various exploration and

Homestake and Barrick.
Geology Deposit type, geological setting and
style of mineralisation.

The Cowal gold deposits (E41, E42, E46, Galway and Regal)
occur within the 40 km long by 15 km wide Ordovician Lake
Cowal Volcanic Complex, east of the Gilmore Fault Zone
within the eastern portion of the Lachlan Fold Belt. There is
sparse outcrop across the Lake Cowal Volcanic Complex
and, as a consequence, the regional geology has largely
been defined by interpretation of regional aeromagnetic and
exploration drilling programs.

The Lake Cowal Volcanic Complex contains potassium rich
calc-alkaline to shoshonitic high level intrusive complexes,
thick trachyandesitic volcanics, and volcaniclastic sediment
piles.

The gold deposits at Cowal are structurally hosted,
epithermal to mesothermal gold deposits occurring within and
marginal to a 230 m thick dioritic to gabbroic sill intruding
trachy-andesitic volcaniclastic rocks and lavas.

The overall structure of the gold deposits is complex but in
general consists of a faulted antiform that plunges shallowly
to the north-northeast. The deposits are aligned along a
north-south orientated corridor with bounding faults, the
Booberoi Fault on the western side and the Reflector Fault on
the eastern side (the Gold Corridor).

Mineralisation within the drilling area is bounded by large
north-south trending structures, however it has strong
internally oblique structural controls. Drill holes are typically
oriented to optimise the angle of intercept at the target
location. All significant intercepts are reported as down hole
intervals unless labelled as Estimated True Widths (ETW).

Criteria Explanation Commentary
Sampling techniques Nature and quality of sampling (e.g.
cut channels,
random chips,
or
specific specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
downhole gamma sondes, handheld
XRF
instruments,
etc).
These
examples should not be taken as
limiting
the
broad
meaning
of
sampling.
Include reference to measures taken
to ensure sample representation and
the appropriate calibration of any
measurement tools or systems used.
Aspects of the determination of
mineralisation that are material to the
Public Report.
In cases where ‘industry standard’
work has been completed this would
be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1
m samples from which 3 kg was
pulverised to produce a 30 g charge
for fire assay’). In other cases more
explanation may be required, such as
where there is coarse gold that has
inherent
sampling
problems,
or
unusual
commodities/mineralisation
types (e.g. submarine nodules).

Sampling of gold mineralisation at Mungari was undertaken
using diamond core (surface) and reverse circulation (RC) drill
chips.

All drill samples were logged prior to sampling. Diamond drill
core was sampled to lithological, alteration and mineralisation
related contacts, whilst RC samples were collected at 1m
downhole intervals. Sampling was carried out according to
Evolution protocols and QAQC procedures which comply with
industry best practice. All drill-hole collars were surveyed using
a total station theodolite or total GPS.

The sampling and assaying methods are appropriate for the
orogenic mineralised system and are representative for the
mineralisation style. The sampling and assaying suitability was
validated using Evolution’s QAQC protocol and no instruments
or tools requiring calibration were used as part of the sampling
process.

RC drilling was sampled to obtain 1m samples using a static
cone splitter from which 3 to 5 kg was crushed and pulverised
to produce a 30g to 50g subsample for fire assay. Diamond
drillcore sample intervals were based on geology to ensure a
representative sample, with lengths ranging from 0.2 to 1.2m.
Surface diamond drilling was half core sampled. All diamond
core samples were dried, crushed and pulverised (total
preparation) to produce a 30g to 50g charge for fire assay of Au.
A suite of multi elements are determined using four-acid digest
with ICP/MS and/or an ICP/AES finish for some sample
intervals.
Drilling techniques Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details
(e.g. core diameter, triple or standard
tube, depth of diamond tails, face-
sampling bit or other type, whether core
is oriented and if so, by what method,
etc.).

RC sampling was completed using a 4.5” to 5.5” diameter face
sampling hammer. Diamond holes from surface were
predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes.

All diamond core from surface core was orientated using the
reflex (act II or ezi-ori) tool.
Drill sample recovery Method of recording and assessing
core and chip sample recoveries and
results assessed.
Measures taken to maximise sample
recovery and ensure representative
nature of the samples.

Whether
a
relationship
exists
between sample recovery and grade
and whether sample bias may have
occurred due to preferential loss/gain of
fine/coarse material.

RC drilling sample weights were recorded for selected sample
intervals and monitored for fluctuations against the expected
sample weight. If samples were below the expected weight,
feedback was given promptly to the RC driller to modify drilling
practices to achieve the expected weights.

All diamond core was orientated and measured during
processing and the recovery recorded into the drill-hole
database. The core was reconstructed into continuous runs on
a cradle for orientation marking. Hole depths were checked
against the driller’s core blocks.

Inconsistencies between the logging and the driller’s core depth
measurement blocks are investigated. Core recovery has been
acceptable. Surface drilling recoveries were generally excellent
with the exception of oxide zones however these rarely fell
below 90%.

Measures taken to maximise sample recovery include
instructions to drillers to slow down drilling rates or reduce the
coring run length in less competent ground.

Analysis of drill sample bias and loss/gain was undertaken with
the Overall MineReconciliationperformancewhere available.

are
appropriate to the grain size of the
material being sampled.

Most diamond core drilled from surface was half core sampled
and the remaining half was retained. In the oxide zone, where
cutting can wash away samples, some surface holes were full
core sampled.

All RC samples were split by a cone or a riffle splitter and
collected into a sequenced calico bag. Any wet samples that
could not be riffle split were dried then riffle split.

Sample preparation of RC and diamond samples was
undertaken by external laboratories according to the sample
preparation and assaying protocol established to maximise the
representation of the Mungari mineralisation. Laboratories
performance was monitored as part of Evolution’s QAQC
procedure. Laboratory inspections were undertaken to monitor
the laboratories compliance to the Mungari sampling and
sample preparation protocol.

The sample and size (2.5kg to 4kg) relative to the particle size
(>85% passing 75um) of the material sampled is a commonly
utilised practice for effective sample representation for gold
deposits within the Eastern Goldfields of Western Australia.

Quality control procedures adopted to maximise sample
representation for all sub-sampling stages include the collection
of field and laboratory duplicates and the insertion of certified
reference material as assay standards (1 in 20) and the
insertion of blank samples (1 in 20) or at the geologist’s
discretion. Coarse blank material is routinely submitted for
assay and is inserted into each mineralised zone where
possible. The quality control performance was monitored as part
of Evolution’s QAQC procedure.

The sample preparation has been conducted by commercial
laboratories. All samples are oven dried (between 85°C and
105°C), jaw crushed to nominal <3mm and if required split by a
rotary splitter device to a maximum sample weight of 3.5kg as
required. The primary sample is then pulverised in a one stage
process, using a LM5 pulveriser, to a particle size of >85%
passing 75um. Approximately 200g of the primary sample is
extracted by spatula to a numbered paper pulp bag that is used
for a 50g fire assay charge. The pulp is retained and the bulk
residue is disposed of after two months.

Measures taken to ensure sample representation include the
collection of field duplicates during RC drilling at a frequency
rate of 5%. Duplicate samples for both RC chips and diamond
core are collected during the sample preparation pulverisation
stage. A comparison of the duplicate sample vs. the primary
sample assay result was undertaken as part of Evolution’s
QAQC protocol. It is considered that all sub-sampling and lab
preparations are consistent with other laboratories in Australia
and are satisfactory for the intended purpose.

The sample sizes are considered appropriate and in line with
industry standards.

and whether acceptable levels of
accuracy (i.e. lack of bias) and
precision have been established.

Fire assay is designed to measure the total gold within a
sample. Fire assay has been confirmed as a suitable technique
for orogenic type mineralisation. It has been extensively used
throughout the Goldfields region. Screen fire assay and
LeachWELL / bottle roll analysis techniques have also been
used to validate the fire assay techniques.

The technique utilised a 30g, 40g or 50g sample charge with a
lead flux, which is decomposed in a furnace with the prill being
totally digested by 2 acids (HCI and HN03) before the gold
content is determined by an AAS machine.

No geophysical tools or other remote sensing instruments were
utilised for reporting or interpretation of gold mineralisation.

Quality control samples were routinely inserted into the
sampling sequence and were also inserted either inside or
around the expected zones of mineralisation. The intent of the
procedure for reviewing the performance of certified standard
reference material is to examine for any erroneous results (a
result outside of the expected statistically derived tolerance
limits) and to validate if required; the acceptable levels of
accuracy and precision for all stages of the sampling and
analytical process. Typically, batches which fail quality control

Independent internal or external verification of significant
intercepts is not routinely completed. The quality control / quality
assurance (QAQC) process ensures the intercepts are
representative for the orogenic gold systems. Half core and
sample pulps are retained at Mungari if further verification is
required.

The twinning of holes is not a common practice undertaken at
Mungari. The face sample and drill hole data with the mill
reconciliation data is of sufficient density to validate
neighbouring samples. Data which is inconsistent with the
known geology undergoes further verification to ensure its
quality.

All sample and assay information is stored utilising the acQuire
database software system. Data undergoes QAQC validation
prior to being accepted and loaded into the database. Assay
results are merged when received electronically from the
laboratory. The geologist reviews the database checking for the
correct merging of results and that all data has been received
and entered. Any adjustments to this data are recorded
permanently in the database. Historical paper records (where
available) are retained in the exploration and mining offices.

No adjustments or calibrations have been made to the final

If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.

Drilling is planned at Castle Hill to intersect ore domains in an
orientation that does not introduce sample bias. A number of
orientations were drilled to target different zones of
mineralisation and to assess the effect on sampling variably
oriented vein sets. It has been noted that the westerly dipping
vein set has not been effectively tested in some parts of the
model. Evolution Mining drilled a number of holes in 2016 to the
east which provided more favorable intersection angles and
tested additional vein sets in some areas. Structural information
gained from this program in conjunction with pit mapping has
informed the search orientation and Resource classification in
the estimate and will contribute to planning future drilling. Some
local bias exists but in the context of a global estimate is not
considered material.

Mineralisation at Perimeter is hosted in a southwest trending
corridor with an average dip and dip direction of 80º /320º.

Mineralisation at Scottish Archer is hosted by northwest
trending structures with an average dip and dip direction of
45º/220º.

Surface holes typically intersect at an angle to the mineralisation
and there is no observed bias associated with drilling
orientation.

The relationship between the drilling orientation and the
orientation of key mineralised structures at Mungari is not
considered to have introduced a sampling bias and is not
considered to be material.

Resource Definition and Exploration drilling is typically planned
to intersect ore domains in an orientation that does not introduce
sample bias. A small number of holes are drilled at sub-optimal
orientations to testforalternate geological interpretations.
Sample security The measures taken to ensure
sample security.

Chain of custody protocols to ensure the security of samples are
followed. Prior to submission samples are retained on site and
access to the samples is restricted. Collected samples are
dropped off at the respective commercial laboratories in
Kalgoorlie. The laboratories are contained within a
secured/fenced compound. Access into the laboratory is
restricted and movements of personnel and the samples are
tracked under supervision of the laboratory staff. During some
drill campaigns some samples are collected directly from site by
the commercial laboratory. While various laboratories have
been used, the chain of custody and sample security protocols
haveremained similar.
Audits or reviews The results of any audits or reviews
of sampling techniques and data.

The Mungari geology and drilling database was reviewed by
acQuire in December 2015 and no material issues were
identified.

Oscillating cone splitters has been in use in the White Foil Pit
for grade control and has returned more consistent duplicate
sample weights than a standard static cone splitter. Trials in the
exploration environment are ongoing.

Exploration has been carried out by a number of parties
including Electrum Resources NL (1985-1989), Castle Hill
Resources NL (1989-1996), Goldfields Exploration Ltd (2001)
and Cazaly Resources Ltd (2004-2008). The historical data and
database have been reviewed by Cube and is deemed to be of
acceptable quality for Mineral Resource estimation.

Significant historical work has been performed across the
Regional Tenement package by numerous parties since the
original discovery of gold in the region c.1890. Recent
exploration commenced during the 1970’s onwards and has
included exploration for base metal and gold mineralisation.

Geology
Deposit type, geological setting and
style of mineralisation.

The Castle Hill Mineral Resource comprises four deposits from
south to north: Wadi, Mick Adam, Outridge and Kiora. The
principal lithology to host gold mineralisation at Castle Hill is the
Kintore Tonalite - a large elliptical intrusive granitoid of
granodioritic composition. The tonalite intrudes a sequence of
basaltic and ultramafic rocks to the east and west. The Kintore
Tonalite attenuates to the south to form a narrow (80m wide in
plan) intrusion which hosts the Mick Adams and Wadi gold
mineralisation. Primary mineralisation within the tonalite at Mick
Adams and Wadi occurs as discrete narrow west dipping quartz
veins containing moderate to high gold grades and as fine
disseminated gold within the tonalite groundmass. Visible gold
has been observed in drill core in both quartz veins and as
blebs in the tonalite groundmass. The disseminated gold is
commonly associated with minor blebs of pyrite, arsenopyrite
and rare chalcopyrite. High grade gold veins are typically 10 to
20cm thick and commonly occur in extensional arrays of four to
five veins generating high grade zones up to 10m in horizontal
thickness. Extensional veins are more common along the
eastern margin of the tonalite. At the southern end of Mick
Adams extensional vein arrays have been intersected in the
footwall of the mafic unit proximal to the tonalite contact.
Extensional shear zone arrays are also the host of the gold
mineralisation at Kiora. Sheeted quartz veins are interpreted as
the extensional veins propagating out from the shears. The
veins within Kiora are hosted within the tonalite along the
contact with ultramafic rocks and have been interpreted as
having undergone supergene enrichment. Gold mineralisation
at Kiora is also hosted within fault fill veins formed by movement
on a shallowly dipping normal fault. Primary mineralisation
within the basalt which forms the immediate hangingwall of the
Mick Adams mineralisation is characteristically associated with
shearing, extensional veining and biotite alteration. This
mineralisation has been called Outridge and comprises a
number of zones which pinch and swell along strike and down
dip and has been interpreted as steeply dipping to the west.

The Perimeter and Scottish Archer prospects are located in the
northern portion of the Mungari tenements, in the Ora Banda
camp. The geology comprises Bent Tree Basalt and Victorious
Basalt. The mineralisation is associated with structures related
to the Grants Patch Fault.

At Frog’s Leg composite grades of > 3 g/t have been reported.

At Castle Hill and other regional properties composite grades
>1 g/t have been reported.

Composite lengths and grade as well as internal significant
values are reported in Appendix.

At Perimeter and Scottish Archer, composite grades > 0.6 g/t
have been reported.

No metal equivalent values are used.
Relationship between
mineralisation widths
and intercept lengths
These relationships are particularly
important
in
the
reporting
of
Exploration Results.
If the geometry of the mineralisation
with respect to the drill hole angle is
known, its nature should be reported.
If it is not known and only the
downhole lengths are reported, there
should be a clear statement to this
effect (eg ‘downhole length, true width
not known’)

There is a direct relationship between the mineralisation widths
and intercept widths at Mungari.

The assay results are reported as down hole intervals however
an estimate of true width is provided in Appendix.
Diagrams
Appropriate maps and sections
(with scales) and tabulations of
intercepts should be included for any
significant discovery being reported.
These should include, but not be
limited to a plan view of drill hole

Drill hole location diagrams and representative sections of
reported exploration results are provided either below or in the
body of this report.

Balanced reporting
Where comprehensive reporting of
all
Exploration
Results
is
not
practicable, representative reporting
of both low and high grades and/or
widths should be practiced to avoid
misleading reporting of Exploration
Results

All Exploration and Resource Definition results have been
reported in the Drill Hole Information Summary in the Appendix
of this report.
Other substantive
exploration data
Other exploration data, if meaningful
and material, should be reported
including
(but
not
limited
to):
geological observations; geophysical
survey results; geochemical survey
results; bulk samples – size and
method of treatment; metallurgical
test
results;
bulk
density,
groundwater, geotechnical and rock
characteristics; potential deleterious
or contaminating substances.

A substantial Exploration and Resource Definition program is
on-going at the Mungari site. Other works include field mapping
and geophysical surveys.
